4WRA6E30-2X/G24K4/V比例方向阀

液压阀的分类:

1根据结构形式分类

滑阀：滑阀为间隙密封，阀芯与阀口存在一定的密封长度，因此滑阀运动存在一个死区。

锥阀：锥阀阀芯半锥角一 般为12°-20°，阀口关闭时为线密封，密封性能好且动作灵敏。

球阀：性能与锥阀相同

2.根据控制制方式不同分:

定值或开关控制阀:被控制量为定值的阀类，包括普通控制阀、插装阀、叠加阀。

比例控制阀:被控制量与输入信号成比例连续变化的阀类，包括普通比例阀和带内反馈的电液比例阀。

伺服控制阀:被控制量与(输出与输入之间的)偏差信号成比例连续变化的阀类，包括机液伺服阀和电液伺服阀。.

数字控制阀:用数字信息直接控制阀口的启闭，来控制液流的压力、流

量、方向的阀类。

3.根据用途分:

压力控制阀、流量控制阀、方向控制阀

方向控制阀的作用:在液压系统中控制液流方向。

方向控制阀包括:单向阀和换向阀

单向阀包括:普通单向阀和液控单向阀

1.普通单向阀

使油液只能沿一个方向流动，反向则被截止的方向阀。

普通单向阀的应用

常被安装在泵的出口，一方面防止压力冲击影响泵的正常工作，另一方面防止泵不工作时系统油液倒流经泵回油箱。

被用来分隔油路以防止高低压干扰。:

与其他的阀组成单向节流阀、单向减压阀、单向顺序阀等复合阀。

安装在执行元件的回油路上，使回油具有一定背压。作背压阀的单向阀应更换刚度的弹簧，其正向开启压力为( 0. 3~0.5) MPa。

比例阀按功能分为三大类

(1)比例压力阀。有溢流阀减压阀,分别有直动和先导两种结构;可连续地或按比例地远程控制其输出油液压力;

(2)比例换向阀。有直动和先导两种结构,直动阀有带位移传感器和不带位移传感器两类。由于使用了比例电磁铁阀芯不仅可以换位，而且换位的行程可以连续地或按比例地变化。因而连通油口间的通流面积也可以连续或按比例地变化。所以比例换向阀不仅能够控制执行元件的方向而且能够控制其速度。因为这个原因比例阀中的比例换向阀应用也为普遍;

(3)比例流量阀。有比例调速阀和比例溢流流量控制阀,可连续地或按比例地远程控制其输出流量。

比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。

4WRA6E30-2X/G24K4/V比例方向阀

类型

4WRA 6 E30-2X/G24K4/V

材料编号

R900904439

设置：

阀门主要包括：

外壳 (1) 带连接面

带压缩弹簧（3 和 4）的控制阀芯 (2)

带中心螺纹的电磁阀（5 和 6）

功能：

对于断电的电磁阀（5 和 6），控制阀芯（2）通过压缩弹簧（3 和 4）的中心位置

通过给比例电磁阀通电直接操作控制阀芯 (2)，例如控制电磁阀“b” (6)

控制阀芯 (2) 向左的位移，与电输入信号成比例

P 到 A 和 B 到 T 的连接通过具有渐进流动特性的孔型横截面

关闭电磁阀 (6)

压缩弹簧 (3) 将控制阀芯 (2) 带回中心位置

带有两个阀芯位置的阀门（类型 4WRA...A...）：

该阀门版本的功能基本上对应于具有三个阀芯位置的阀门。但是，该 2 阀芯位置阀仅配备电磁阀“a”。有一个带 NG 6 的堵头螺钉 (8.1) 或带 NG10 的盖板 (8.2)，而不是第二个比例电磁铁。

注意：

不得让油箱管路空转。在相应的安装条件下，必须安装一个预紧阀（预紧压力约 2 bar）。

减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。
